Import your drill collar CSV (columns: hole ID, latitude, longitude, depth, assay)
Assign the Drillholes layer role
Import the property claims boundary as GeoJSON
Add callout labels to key holes showing hole ID and best intercept
Use Badge Label type to highlight the highest-grade holes
Configure the title with program name and date
Set the Landscape 16:9 ratio for news release figures
Export as PNG at 2× for email and PDF for the news release attachment
